Hagia Sophia is dedicated

node

The church is dedicated five years after work began - an extraordinarily short campaign for a building of that ambition, and part of why the first dome failed. The interior sets a dome roughly 31 m across on four piers by means of pendentives, and the two half-domes to east and west absorb the thrust along the long axis so that the space reads as one continuous volume.

A node is not a place. Drawing it on a map would assert something about the world that no stored fact supports.
